Abstract: A brake source select system for selecting one of a plurality of sources of pressurized hydraulic fluid for use in actuating a brake system. The brake source select system (10) includes a primary, secondary and reserve source (20, 22 and 24) of pressurized hydraulic fluid connected in fluid communication respectively to a primary selector valve (32), a secondary selector valve (96) and a reserve selector valve (102). Pressurized hydraulic fluid from the primary source (20) is applied to deselect ports (94 and 100) on the secondary and reserve selector valves, causing those valves to block fluid flow from their associated sources to the brake system, so long as the primary source is operative. Upon failure of the primary source, pressurized fluid is no longer applied to the deselect port of the secondary selector valve, thereby enabling fluid flow through the valve, and causing pressurized hydraulic fluid from the secondary source to be applied to the deselect port (160) of the reserve selector valve and to a deselect port (164) of the primary selector valve, effectively blocking fluid flow through each of those valves. Should the secondary source fail, elimination of the pressurized fluid applied to the deselect port of the reserve selector valve enables it to conduct pressurized hydraulic fluid to the brake system, and applies the pressurized hydraulic fluid to the primary and secondary selector valve deselect ports, blocking fluid flow through those valves. Thus, failure of a higher priority source automatically results in selection of a next lower priority source to provide pressurized fluid to the brake system. In addition, a source of pressurized fluid associated with retraction of a landing gear is applied to a selection port (208) of the secondary selector valve, causing that valve to provide a source of pressurized hydraulic fluid to actuate the brakes, slowing the rotation of wheels prior to full retraction of the landing gear.

Abstract: The invention relates to an antenna for receiving and modulating transmitted signals having a very low power density on the order of below 1 watt per meter squared, at a selected center frequency above 2,000 MHz. The antenna uses a folded planar dipole section having two separated oppositely disposed U-shape elements, each of said elements having a pair of ends. A capacitor is series-coupled between two of the oppositely disposed ends of the elements, and a diode having a high impedance at the selected center frequency is series-coupled between the other two oppositely disposed ends of the U-shape elements. A metallic backplane is mounted parallel to the planar folded dipole section and spaced from the dipole section a predetermined distance selected to reduce the antenna impedance. The impedance of the diode, the shape of the folded planar diode section and the predetermined amount of spacing of the backplane from the planar folded dipole section are all selected to increase the d.c. power output of the antenna.

Title: Improved safety trocar
Inventor: DENIEGA JOSE C
IPC: A61B17/34
Filed: 1989-07-05
Abstract: A safety trocar is provided which includes a spring-loaded shield (32) that shields the cutting tip of the obturator after the obturator penetrates tissue. The distal end (34) of the shield is hemispheric in profile and contains a slot which conforms to the geometry of the cutting tip. The rounded distal end enables the shield to spring forward to shield the cutting tip as soon as the tip perforates the tissue. A valve is located at the proximal end of the trocar tube to seal the end of the tube. The valve is oriented at an acute angle with respect to the longitudinal axis of the trocar tube. The valve is controllable by an external lever which will hold the valve open or permit it to spring shut. An incremental advancement mechanism cooperates with the obturator to permit only incremental advance of the obturator. Instead of using a discrete shield component the shielding function may be provided by spring-loading the trocar tube itself to spring forward and shield the obturator tip after the tip penetrates tissue.

IPC: G01G19/14
Filed: 1989-08-09
Abstract: Elevator load is computed from sensors. These sensors provide load signals. The load, defined by a stored load equation, is the product of those signals with a gain signal, summed with an offset signal (S20). Load computation using those signals is improved by a recalibration routine. The routine to adjust the offset (S2-S10) is initiated when the car transits floors in an empty car condition (S2). Current equation offset and the latest empty car signal levels are compared (S6). If the difference is less than a reference (STEP) the last levels become the offset (S9); if not, the equation offset is changed (S7). Load computation is further improved by sensing car rollback, to correct the gain signal. Rollback may occur after the brake holding the car in position is released but before a speed dictation signal is given to the motor, causing the car to move if motor torque is not matched to the load as computed from the load equation. Depending on the magnitude of the rollback, the gain is increased or decreased in increments (S23-S41) through successive elevator stops at floors provided there is sufficient passenger (cab) load. Rollback not caused by incorrect motor pretorquing when the brake is released is discarded (S21) by comparing the actual change in position of the car with the change in motor shaft or sheave position.

Abstract: A position detecting apparatus (Fig. 1) usable for aligning a mask (15) and a semiconductor wafer (16), wherein a laser beam (14) produced by a semiconductor laser (1) is projected through a predetermined optical system to alignment marks (15a,16a) formed on the mask (15) and the wafer (16), and the light (17) reflected by the marks is detected by an accumulation type sensor (4) to produce an electric signal, from which the relative positional relation between the mask (15) and the wafer (16) is detected on the basis of the electric signal. To obtain proper mark signals, the quantity of light incident on the accumulation sensor (4) is controlled. In this apparatus, the beam emitting strength of the semiconductor laser (1) is made constant, and the control of the amount of light incident on the accumulation sensor (4) is effected by controlling (2) the operation period of the semiconductor laser (1). In addition, the actuation timing (7) of the semiconductor laser (1) is advanced from the accumulation start of the accumulation type sensor (4) by the time (Ts) required for the semiconductor laser (1) to be thermally stabilized after its actuation. The mark detection signal produced by the accumulation sensor (4) is precise.

Abstract: The present invention relates to methods for treating infectious diseases in animals by initiating qualitative and quantitative changes in the phagocytic cells of said animals. This activation occurs by the administration of a phagocytic-cell activating agent, such as immunomodulators; cytokines such as inter­leukins (interleukin -1, 2, 3, 4, 5, 6 and 7), inter­ferons and colony stimulating factors; antimicrobials such as mucolytic enzymes, lysozyme, lysostaphin; complement and its components; chemotractants such as lipopolysaccharide and zymosan activated cow sera. The appropriate activation of the phagocytic cells in the animal for effective therapy requires not only an increase in the total number of cells which phagocytose cell particles, but also an increase in the number of particles phagocytosed per cell, intracellular killing. Thus, the present invention also relates to a method for measuring the efficiency of phagocytic-activating agents to predict and monitor appropriate therapy.

Abstract: In a radio communication apparatus (11) for receiving radio signals at a predetermined period when a power source switch (14) is put in an on state and when the apparatus is in a service area (13) of a base station (10), a timer circuit (31) times a preselected time interval substantially equal to the predetermined period from a time instant at which the switch is turned from an off state to the on state. The timer circuit produces a time-out signal when the timer circuit times the preselected time interval. Each radio signal carries a synchronization signal and an additional signal. A detecting circuit (32) detects a timing at which a synchronizing circuit (21) is in a synchronized state. In the synchronized state, a tiaing clock signal produced by a clock generating circuit (20) is synchronized with the synchronization signal. The detecting circuit produces a detection signal when the detecting circuit detects the timing before reception of the time-out signal. When the detecting circuit does not detect the timing before reception of the time-out signal, the detecting circuit produces the time-out signal as a non-detection signal. An announcing arrangement (19, 25, and 27) announces in response to the detection signal and the non-detection signal that the apparatus is and is not in the synchronized state (namely, the apparatus is and is not present in the service area), respectively.
